Markwalder Marabu

04/30/2010. Remarks by Johan Visschedijk: "Best known as designer of the Elfe series of high-performance sailplanes, Ing. A. Markwalder of Räterschen, Switserland has also designed an all-wood three-seat light aircraft named the Marabu. Stress calculations were done by Prof Raucher of the Ecole Polytechnique Federale and the prototype was completed by Ernest Barfüss, a garage-owner of Fehraltorf, near Zurich.

Design of the Marabu was started in July 1960 and construction of the prototype began in the following September of the same year. Fitted with an 150 hp Lycoming O-320 four-cylinder horizontally-opposed air-cooled engine, it flew for the first time on August 28, 1965, with Ueli Häusermann at the controls. As manufacturer is also reported Barfüss (as it still is registered) and Uetz (Markwalder was a constructor for the Flugzeugbau-Firma Uetz at Fehraltorf).
